The Bluetooth Technology
The Bluetooth technology creates a small wireless network between computers and peripheral devices, such as keyboard and mouse. Bluetooth is named after Herald Bluetooth, who was the king of Denmark and Norway in the 10th century.
The Bluetooth technology allows you to transfer data at the speed of 723 Kilobits per second (Kbps) to 1 Mbps within the range of 10 meters.
The working of Bluetooth devices is based on a master/slave model. This model contains 266 devices out of which one is a master device and 255 are slave devices. Any device can be master and the master device can select up to seven slave devices and communicate with them simultaneously.
Discussing the Features of the Bluetooth Technology
The features of the Bluetooth technology are as follows:
Wireless synchronization: Provides automatic synchronization between Bluetooth enabled devices.
Avoids interference from other wireless devices: Allows you to prevent data intrusion across Bluetooth devices and other wireless devices connected through Bluetooth by using the Frequency Hopping Spread Spectrum (FHSS) method.
Ease of file sharing: Allows you to share data between Bluetooth compatible devices connected via Bluetooth easily.
Working of the Bluetooth Technology
The Bluetooth technology has an authentication feature, which ensures that you are communicating with a right person. With this function, you can prevent any anonymous Bluetooth device from accessing your computer, PDA, or mobile phone.
You must note that you need to register a common Passkey for two Bluetooth devices which are communicating for the first time. After registering the devices, you need not to specify the Passkey again in the future. Moreover, you can change the settings of the Bluetooth device, so that other Bluetooth devices do not discover your Bluetooth device. In addition, the Bluetooth technology also offers proprietary 128-bit encryption and capability to set a user name and password to guard against any unauthorized access to a Bluetooth network.
The Bluetooth technology can be used either to create a wireless connection between the Internet and a device, or between a computer and other devices.
